Aluminum is a popular metal powder for additive manufacturing thanks to its low density, good mechanical properties, machineability, corrosion resistance and conductivity. Optimizing aluminum powder characteristics enables reliable printing of strong, lightweight aluminum parts across aerospace, automotive and industrial applications.<\/p>\n\n\n\n

This guide covers properties, specifications, atomization production, quality assurance considerations, applications and advice on sourcing aluminum powders for powder bed fusion or binder jet 3D printing.<\/p>\n\n\n\n
